The first step needling non-woven fabric is made of polyester and polypropylene fiber, through carding, combing, pre needling and main acupuncture. The center is interbed with the net cloth, and then through the double channel core, the air flow is formed by the mesh needle, and the back pressure filter fabric has a three-dimensional structure and is finalized by heat. 第二步烧毛后，在表面最经化学油剂处理，使滤布外表光滑，微孔分布均匀，从表面看该产品的密度好，两面表面光洁和透气程度较好，在板框压缩机上过滤使用证明，可使用高强压力，过滤精度高达4微米以内，可根据用户需要提供丙纶和涤纶两种原料。 The second step after singeing, on the surface of the oil by chemical agent, make cloth smooth appearance, uniform pore distribution, from the surface of the product density, good surface finish and two air filter, that can be used in the frame on the compressor, high pressure filtration precision up to 4 microns, can provide two kinds of raw materials of polypropylene and polyester according to user needs. 实践证明无纺过滤布在板框压滤时性能更好：例选煤厂的煤泥处理，钢铁厂废水处理。在啤酒厂、印染厂废水处理。如用其他规格滤布都会出现滤饼压不干，又难以脱落的问题，用无纺滤布后，滤饼在滤机压力到达10kg-12kg时就相当干燥，而滤机开框时滤饼会自动脱落。用户在选择无纺滤布时，主要根据透气量，过滤精度、伸长率等来考虑不同厚度、质量的无纺滤布，产品参数请点涤纶针刺毡和丙纶针刺毡，规格品种均可制定。 Practice has proved that the non-woven filter cloth have better performance in plate filter: Coal Washery wastewater treatment, treatment of iron and steel plant. Wastewater treatment in the brewery and printing and dyeing plant. If there are other specifications of filter cloth, there will be a problem that cake pressure is not dry and it is difficult to fall off. After using the nonwoven filter cloth, the filter cake will be quite dry when the pressure of the filter reaches 10kg-12kg, and the filter cake will fall off automatically when the filter opens. When choosing non-woven filter cloth, the users mainly consider different thickness and quality non-woven filter cloth according to air permeability, filtration accuracy and elongation. The product parameters can be made of polyester needled felt and polypropylene needle felt, and specifications and varieties can be formulated. |
